Possible reasons for the automatic transmission jerking when starting off:
1. Dirty or poor quality gear oil:
* The oil loses its lubricating properties and causes friction in the gearbox.
* Replace the gear oil with the type and brand recommended by the manufacturer.
2. Worn oil filter:
* The filter becomes clogged with particles and dirt, restricting oil flow.
* Replace the oil filter at the same time as changing the oil.
3. Faulty speed sensor:
* The sensor does not accurately tell the transmission about vehicle speed, resulting in incorrect gear shifting.
* Replace the speed sensor.
4. Slipping or worn clutch:
* A worn or slipping clutch can cause harsh shifting noises.
*Adjust or replace the clutch if necessary.
5. Problems with solenoids:
* Electromagnetic solenoids control gear shifting in an automatic transmission.
* Faulty solenoids can cause jerking when shifting.
* Diagnose and replace faulty solenoids.
6. Mechanical problems:
* Worn or broken transmission components, such as gears, synchronizers, or shafts, can cause shifting to jerk.
* Repair or replacement of faulty parts.
7. Electrical wiring problems:
*Damaged or frayed wires or connectors may affect transmission performance.
* Check and repair or replace damaged electrical wiring components.
8. Software problems:
*In some cases, software issues may cause the transmission to jerk.
*Update or reprogram the transmission software.
Important: If you experience transmission jerking, take it to a qualified mechanic for diagnosis and repair. Ignoring this problem can result in further damage to the transmission and costly repairs.
